Be warned this is a spell for quick death. Don't do this if you want to be safed the least.
Do it outside at night.
Mother of Darkness ,hear my plea i wish to be a vampire.To have long fangs,red eyes and pale skin.To sell my soul to you.To thrive on blood.To have super strength and speed. So mote it be.
Latin version.
Mater Dei, Dómino meo audire velim causa esse vampire.To tempore habent saevire dente iam ruber oculis pallidus skin.To vendere animam meam ut non Super blood.To you.To uiuit cum principiis vires et celeritate. Sic fiat semper.
P. S. You have been warned.
